GENEVA, Feb 2 (Reuters) - The Zika virus linked to a
microcephaly outbreak in Latin America could spread to Africa
and Asia, and the World Health Organization will set up
monitoring sites in the poorest countries with the highest birth
rates, it said on Tuesday.

The WHO on Monday declared an international public health
emergency due to Zika's link to thousands of recent birth
defects in Brazil.

It called for the urgent development of better diagnostic
tests to detect the virus in pregnant women and newborn babies.
Seen as a relatively rare condition, the virus may lead to
babies being born with small heads and often experiencing
neurological disorders and learning disabilities.
